4 Claims.

'Ihis invention relates to improvements in signal devices and pertainsparticularly to a signal device designed for -use in association with adispensing apparatus.

The primary object -of the present invention is to provide a devicedesigned for application to a dispensing faucet, upon which a receivingreceptacle may be suspended and which will indicate by an unmistakablesignal when a predetermined quantity vof fluid has passed into thereceptacle.

Another object -of the invention is to provide a sig-nal device of theabove described character which is of simple design, leasily attached toor detached `from a dispensing faucet, and requiring little attentionAto 'keep in order.

'The invention will 'be ybest lunderstood from a consideration ofthefollowing Vdetailed description taken in connection with theaccompanying drawing forming part v`of this specification, with theunderstanding, however, that the invention is not confined to any strict`conformity vwith the showing -of the drawing but may be changed -ormodified so longas such-changes or modifications mark no materialdeparture from the salient features of the invention as expressed in theappended claims.

In the drawing:-

Figure 1 is a view -illustrating the application of the device embodyingthe present invention to a dispensing faucet and showing, in brokenlines, a receptacle suspended therefrom;

Figure 2 is a view of the interior of `the device looking at the samefrom the rear, portions being in section;

Figure 3 is a vertical sectional view taken substantially upon 'the line3-3 of Figure 2;

Figure 4 is a sectional view taken substantially upon the line 4 4 -ofFigure 3.'

Referring now more particularly to the-drawing wherein like numerals ofreference indicate lcorresponding parts throughout the several views,the numeral I indicates a faucet of the type commonly employed von tankwagons in which gasoline, oil or Aother liquids are transported. Fromthese vwagons fthe liquid is drawn off through the faucet intoAreceptacles of diiferent capacities, for sale.

The device'embodying the present invention is designed to be attachedtothe pipe 2 with which the faucet r`I is connected and is indicated asa whole by the numeral 3.

The device 3 comprises a casing III having a transparent front panel 5and a removable back Lwallfii. Connected with the casing is aclamp ofBronaugh, Mo.

a suitable character, such for example as the split ring clamp l, theends of which are drawn together by a connecting bolt 8, by means ofwhich the device is attached to the pipe 2 to be suspended therefrom.

Within the casing Il is mounted, in spaced relation with the transparentrpanel 5, the dial 9, the outer face of which is viewable through theglass panel 5 and bears an annular series of notations which in thepresent case are illustrated as run- 10 ning by ves from zero to onehundred. These notations in the present instance represent gallons ofliquid.

Extending through the radial center of the dial 9 and through the back 6and passing through 15 the casing 4, is a shaft ID upon the forward endof which is a signal indicator hand II which rotates over the face ofthe dial behind the glass panel 5.

Upon the opposite side of the casing and the 2o other end of the shaft I0, isa key I2 by means of which the shaft may be rotated when and asnecessary.

Within the casing 4 there is secured the body I3 against the back of thedial S and the shaft 25 I0 passes through the center of this body.Pivota'lly mounted upon the body I3 at the point I4 is a pawl YI5 whichis integral with the elongated tail-piece .IG which terminates in anangularly extending arm I l. Upon this arm `I1 is 30 fixed a hammer I8.

Mounted kupon the back of the dial 9 isa bell I9 adjacent which thehammer I8 .is disposed and with which the hammer comes in contact duringthe operation ofthe device to give the de- 35 sired signals.

A pin 2B mounted upon the back of the dial 10 has secured thereto oneend of a flat spring 2I which intermediate its ends extends across andis in contact witha stop pin 22. Connected 40 vwith the free end of thespring 2| is a link '23 through which the tail-piece IS of the ,pawlpasses.

Mounted upon the shaft l0 for free rotation therewith, is a drum 24having a flange 25 in 45 which are formed the teeth 2S. Upon the back ofthe drum 24 is a ratchet 21 with the teeth of which the pawl I5 engages.

The shaft vIS extends through one end of a lever arm 28 and the armrocks freely on this 50 shaft. This arm 28 passes across the toothededge 25 of the drum 24 and extends through an aperture 29 in the wall ofthe casing 4, terminating at its outer end, exteriorly of the casing 4,in the Ahook 3D. 'The loweredge of this ap- .55

, erture 23 limits the downward movement of the arm 2&3 and as the armis swung down its lower edge, which is in contact with a tooth 25,causes a partial rotation of the drum 2li upon the shaft. The lever arm2B is of suitable iiexibility to permit it to bend slightly laterally topass over the teethi in its reverse movement on the shaft. Suitablemeans is employed for retaining the arm 28 in its proper position on theshaft, such for example, as the collar Si. This retains the inner end ofthe arm in place.

Extending through a boss 32 upon the outside of the wall of the casingis a threaded stem 33 with which is engaged a nut Sli which rests uponthe boss.

provide a hook 35. Surrounding the bifurcated portion of the stem 33 isa coil spring 35, the

lower end of which rests against the hooks 35. The upper end of thespring 35 is connected with a linke? which passes downwardlytherethrough and has engagement with the arm 25 as is clearly shown inFigures 2 and 4. By the adjustment of thernut 3ft upon the stem 33 thetension of the spring can be'Y increased or decreased as it will tend topull the arm upward while its movement is limited by the Yupper edge ofthe aperture 29. j In the operation ofthe present device after thesamehas been attached to a faucet pipe as illustrated in Figure l and thenut 313 adjusted to properly tension the spring 36, when a receptacle,such as is indicated at 38, is suspended from the hook 3i it will bedisposed beneath the faucet Vl to receive iiuid therefrom and when thefaucet is opened and an amount of iiuid equal to five gallons has flowedinto the receptacle, the arm 28 will have been pulled down to the pointwhere, through its contact with one of the teeth 25, the drum 2e willhave been rotated sufficiently to cause a tooth of the ratchet 2 to passthe point of the pawl l5. As the tooth of the ratchet 2'! Vis ridingunder the point of the pawl l5 the tail portion le of the pawl will beswung so as to Vflex the spring 2| and when the pawl snaps off of thetooth the hammer I8 will be caused to vsnap back against the bell, Vthussignalling tothe attendantthat the receptacle 3S contains apredetermined amount of the liquid.

Itis, of course, to be understood that various `adjustments of thetension of the spring 35 must lthe device may be used continuously forthe same .iiuid and with the same receptacle to measure off ments may bemade to suit the convenience of the Y user and the invention is not tobe restricted to the particular form and arrangement illustrated.
